liiririi gieten Letters Patent No. 98,675, dated January' 11, 1870.

The Schedule referred to .in these Letters Patent and making pari: of the same `To all whom it 'may concern:

l Be it known that I, ISAAC Diners, of Fort Wayne, in the county of Allen, and Stn-te of Indiana, have in- Vvente-dn. new and useful Improvement in Railroad- `through the line aref, iig. 1.

Figure'B is a detail top view ofthe middle part of one side of the truck. v

Figure 4 is a detail sectional view of the same, taken through the line y y, fig. 1.

My invention has for its object to furnish an improved rnilroad-car truck, which shall be simple in construction, strong and durable, cannot be knocked out of square, and will be sniciently ilexible to allow each side ofthe truck-fiume to accommodate itself to inequalities ot track, thereby relieving the wheels from any undue shocks from bad joints or other nnei'enness of the rails; and

It consists in the construction and combination of various parts of' thetruek, as hereinafter more fully l decribed.

A are the wheels;

B yare the journal-boxes; and Y C are the iron frames connected with and connecting the journal-boxes B.

l) are iron frames placed between the upper and lower bars oi' the frames` (Lend which are securely bolted to the said frames C` bythe bolts lll passing down through the uprights of said frames D, as shown.

E is the lower plu-nk or timber, which is made wide and thin, to give the necessary iexibil-ity to the truck, and the ends of which rest upon the lower bars of the frames C, und against the upwardly-projecting basebar or flange of the frames D,ns shown in figs. 2 and 4.

The ends of the timber E are secured to the lower parts of the fiume C by the vertical bolts c', and to the frames D by the horizontal bolts gli.

F is the upper plank or timber, which rests upon and is supported by rubber blocks, or other springs placed between the two timbers E F.

Thcends of' the timber or plank F pass beneath the top bars of the frames C, and between the upright parts ofthe frames D, with which snid uprights they are connected7 und :it the sinne time inode to nmveup and down vertically by the lunido-blocks G attached to the edges of the timber F, and the outer sides of which are notched or recessed to receive und slide up and down upon the said uprights ofthe said frames D.

H are the brace and tie rods, the middle parts of' which pass beneath the lower ends oi' the blocks or knees I attached to the under side-ofthe middle part of the lower plank lil, and the cnds of which poss through the base-bars or innges of the frames I), :is shown in figs. l, 2, and 4, where they arc secured by nuts.

By this construction and arrangement, the more weight that is applied to the truck, the firmer will the frames D be forced against the ends of the plank E, so that so long as the tie-rods or bolts H remain unbroken, the truck-flames cannot be Y knocked to pieces.

'Having thus described my invention, I clnini as new, and desire to secure by Letters Pntent* l The combination ot tie and brace-rods H, with lower timber E and frames D, all arranged as and for the purpose set forth.

ISAAC DRIPJTS.
